Comment: C: Found gaps in scan time of file : cut scantime-vector at NA seconds. Error: Bioc
... Don't worry about the `x$.self$finalize()` calls - I did not find a way yet to get rid of them, but they don't affect the analysis. They occurr randomly. Now regarding the issue that you get, would it be possible for you to share the *BN_amide_092.mzXML* file and a second one of your files? It's ha ...

Comment: C: Found gaps in scan time of file : cut scantime-vector at NA seconds. Error: Bioc
... Dear Abbey, thank you for your detailed description of your issue! The error that you see comes from the *obiwarp* alignment. Without knowing your data it is now difficult to get to the exact cause, but I guess that obiwarp has a problem with the retention times in one file (e.g. because, as the er ...

Comment: C: xcms centwave roiList error
... Note that you can also provide a `matrix` with arguments `mz` and `rt` (two columns with lower and upper boundary, each row defining the region in wich you expect the data from one ion). With that you could extract multiple XIC at once and you could also run the `findChromPeaks` on all of them. That ...

Comment: C: xcms centwave roiList error
... The `findChromPeaks` function is really only intended to identify chromatographic peaks - not to extract ion chromatograms. To extract ion chromatograms you have to use the `chromatogram` function on the *on disk* data. It will extract the chromatogram for each file in your data. If you call `plot` ...

Answer: A: xcms centwave roiList error
... The `roiList` parameter should be a `list`. So what you should do is to provide the ROI as: ``` Trypto <- list(c(scmin = 51, scmax = 800, mzmin = 216.1321, mzmax = 216.1361, length = 20, intensity = 1000)) cwp <- CentWaveParam(roiList = Trypto) ``` Note however that it would be much easier t ...

Answer: A: Extracting Data from MSn experiment data ("OnDiskMSnExp")
... Hi James, the reason the `write.table` function takes so long is that in that call all processings are applied to the data. In the *on disk* mode all data manipulation operations are *cached* and only applied whenever you access the data (which in your case is when you call `write.table`, which in ...

Comment: C: XCMS - cannot allocate vector of size **Gb when global environment is empty
... Two things: 1) please change to the *new* functions/objects of `xcms` (see [xcms vignette](https://bioconductor.org/packages/release/bioc/vignettes/xcms/inst/doc/xcms.html)). 2) `profstep = 0.01` will create a huge matrix (which in your case will not fit into memory) - question is if you really nee ...
